The bis-guanidinate stabilized, structurally characterized gallium dihalides (Ga−Cl, Ga−I) and dihydride (Ga−H) compounds are reported. Gallium hydride (Ga−H) is an effective catalyst for the chemoselective reduction of heteroallenes with HBpin. Moreover, Ga−H is a potent catalyst for the hydroboration of imines, nitriles, alkynes, esters, and formates, yielding the corresponding hydroborated products.

氢化镓催化不饱和有机底物的选择性硼氢化

报道了双胍盐稳定的、具有结构特征的二卤化镓 ( Ga−Cl, Ga−I ) 和二氢化镓 ( Ga−H ) 化合物。氢化镓 ( Ga−H ) 是 HBpin 化学选择性还原杂联烯的有效催化剂。此外，Ga−H是亚胺、腈、炔烃、酯和甲酸酯硼氢化反应的有效催化剂，可产生相应的硼氢化产物。
